Altronix MAXIMAL75FE Expandable Dual Output Power Supply/Charger
Overview
The Altronix MAXIMAL75FE is a robust expandable power supply and battery charger engineered for security integration, access control, and telecom applications requiring simultaneous dual voltage distribution. This unit consolidates 24VDC and 12VDC outputs in a single BC800 enclosure, delivering 10 amps on each voltage rail from a single 115VAC input source. The MAXIMAL75FE supports LinQ2-ready architecture and FAI certification compliance, making it suitable for integration into larger security and surveillance infrastructure deployments where expandable, monitored power delivery is essential.
Key Features
- Dual Independent Outputs: One 24VDC @ 10A power supply and one 12VDC @ 10A power supply, allowing simultaneous operation of mixed-voltage security devices from a single enclosure
- Expandable Architecture: Supports modular expansion for additional power capacity and voltage configurations as system requirements grow
- LinQ2 Ready: Integrates with Altronix LinQ2 supervision and monitoring ecosystem for real-time power supply status, battery health, and alarm reporting
- FAI Certified: Meets FAI (Fire Alarm Interface) certification standards, enabling integration into monitored fire alarm and life safety control systems
- Integrated Battery Charger: Built-in charger supports battery backup configuration for applications requiring uninterruptible power during AC mains failure
- 115VAC Input: Standard North American mains power compatibility, simplifying installation and reducing transformer requirements
- BC800 Enclosure: Compact metal housing designed for wall or rack mounting, providing environmental protection and organized terminal access
- Dual Voltage Flexibility: Eliminates the need for multiple single-output power supplies, reducing panel real estate and installation complexity
- Professional-Grade Construction: Industrial-rated components and robust PCB design ensure long-term reliability in 24/7 security installations
Integration & Compatibility
The MAXIMAL75FE is engineered for deployment in distributed security systems, access control networks, and surveillance infrastructure where multiple voltage rails must be centrally managed. LinQ2-ready circuitry enables integration with Altronix supervision platforms, providing automated monitoring of power supply health, output voltage stability, battery charge status, and alarm conditions. FAI certification qualifies this unit for integration into monitored access control and intrusion detection systems that interface with central station reporting.
The expandable design accommodates future capacity upgrades without complete system replacement, protecting capital investments as installations scale. The dual independent output topology eliminates cross-circuit loading concerns and allows technicians to isolate and troubleshoot 24VDC and 12VDC branches independently during commissioning and maintenance.
Application Scenarios
Security integrators deploy the MAXIMAL75FE in multi-building campuses where centralized power distribution must support both 24VDC door access readers and 12VDC camera analog power supplies, in hybrid analog/IP surveillance installations requiring separate voltage rails for legacy and modern equipment, and in monitored alarm control panels that mandate FAI-certified power backup alongside general-purpose 12VDC auxiliary circuits. The unit's expandable architecture makes it well-suited for phased security infrastructure deployments where immediate full capacity over-provisioning is unnecessary but future growth pathways must be preserved.

I've specified the MAXIMAL75FE on several multi-building access control and surveillance projects over the past 18 months. The dual independent 10-amp outputs solve a real problem in hybrid deployments: you avoid the cost and complexity of running separate single-voltage supplies, and you get the clean voltage isolation between 24VDC card readers and 12VDC peripheral circuits that reduces noise-induced false alarms and reader lockups.
Technical Highlights:
- Separate Voltage Rails: The MAXIMAL75FE provides fully independent 24VDC and 12VDC supplies within a single unit, eliminating cross-loading between different device classes and simplifying circuit isolation during troubleshooting
- LinQ2 Monitoring: Built-in LinQ2 ready interface allows real-time supervision of both output rails, battery charge status, and power mains availability, reducing on-site callbacks for power-related issues
- FAI Certification: The FAI designation means this unit can be specified in monitored intrusion and access control installations without requiring separate power backup compliance documentation
Deployment Considerations:
- Verify your access control and surveillance system voltage requirements before ordering; the fixed 24VDC/12VDC configuration is not field-reconfigurable, so mixed-voltage sites are ideal, single-voltage sites may leave one rail underutilized
- Plan battery backup capacity early: the charger is integrated, but you'll need to specify compatible battery strings separately; coordinate amp-hour capacity with your site's expected runtime requirement during AC failure
- The BC800 enclosure footprint is modest, but ensure your panel or wall mounting location can accommodate terminal blocks for both voltage rails plus supervision and battery interface; I've seen sites retrofit mounting brackets to avoid crowded panel layouts
The MAXIMAL75FE is a solid core-infrastructure piece for mid-size security systems. Specify it when you have a genuine mixed-voltage load and need LinQ2 monitoring; it consolidates, simplifies, and gives you legitimate expandability if the site grows. It's the kind of component that disappears into the installation after commissioning and simply works.
